Hemispatial neglect is a neuropsychological condition in which, after damage to one hemisphere of the brain (e.g. after a stroke), a deficit in attention and awareness towards the side of space opposite brain damage (contralesional space) is observed.
In Tan's autopsy, Broca determined he had a syphilitic lesion in the left cerebral hemisphere. This left frontal lobe brain area (Broca's area) is an important speech production region. The motor aspects of speech production deficits caused by damage to Broca's area are known as expressive aphasia. In clinical assessment of this type of aphasia ...
Pure motor stroke/hemiparesis (most common lacunar syndrome: 33–50%) posterior limb of the internal capsule, basilar part of pons, corona radiata It is marked by hemiparesis or hemiplegia that typically affects the face, arm, or leg of the side of the body opposite the location of the infarct.
Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [2]
Emotional lability occurs in about 20% of those who have had stroke. Those with a right hemisphere stroke are more likely to have empathy problems which can make communication harder. [234] Cognitive deficits resulting from stroke include perceptual disorders, aphasia, [235] dementia, [236] [237] and problems with attention [238] and memory. [239]
Watershed stroke symptoms are due to the reduced blood flow to all parts of the body, specifically the brain, thus leading to brain damage. Initial symptoms, as promoted by the American Stroke Association, are FAST, representing F = Facial weakness (droop), A = Arm weakness (drift), S = Speech difficulty (slur), and T = Time to act (priority of intervention).
The second, the ipsilateral pathway, allows for the transmission of information along the same side of the body (i.e., the left side of the body to the left hemisphere). [ 15 ] In a healthy individual, when a hand is stimulated by touch, there is increased brain activity in the contralateral hemisphere, and decreased activity in the ipsilateral ...
This leads to poor oxygen supply or cerebral hypoxia and thus leads to the death of brain tissue or cerebral infarction/ischemic stroke. [2] It is a sub-type of stroke along with subarachnoid hemorrhage and intracerebral hemorrhage. [3] Ischemia leads to alterations in brain metabolism, reduction in metabolic rates, and energy crisis.
